[TowerTalk] Adding 15 meters to a 204BA

[john at kk9a.com]

Maybe easy for you, Stan  I have not done well designing multi-band Yagi's although I have not tried doing so with AutoEZ.  I would be interested in seeing your WEQ file for this.  Hy-Gain uses a large formed aluminum element clamp so you might have to make some guesses for modeling.  Insulated elements are easier.

Dave,

This is pretty easy to do.  Would probably end up being 3 on 20 and 4 or 5 on 15.  The difficult part is inputting exactly what the lengths and diameters you are going to use for each element.  AutoEZ will do the rest of the work using one feedline.

If you give me the exact lengths and diameters of the first 3 elements on your 20m antenna and same info for what you want to use for the 15m elements, I’ll do it for you.

No 10 meters?
